    Hi @PCN, Wu, Rock (IT) ,

    Welcome to our forum!

    In order to verify your issue, could you please provide some detailed information:

    1. What detailed version of Outlook are you using? Please make sure that you upgrade it to the latest.
    2. What type of account are you using?

    Based on my search for this error, this issue may be caused by several reasons.

    As I know, any anti-virus programs may also affect the connectivity of Outlook and server, it's suggested to close other antivirus programs temporarily to check if the issue still exists.

    Since the issue occurred only recently, in order to avoid the interference of corrupted outlook profile, it's suggested to create a new outlook profile and readd your account to check.(control panel>mail>show profiles>add>readd your account)

    If above doesn't help, Repair Office from Control Panel.
